Chapter 1. Electricity, Waves, and Pulses
Definition of electrical engineering. Nature of electricity due to charged particles. The fundamental quantities of voltage and current. Effects of electrical charge. Units of measurement. Steady (DC) and alternating (AC) voltages. Sources of steady voltage such as batteries (cells) and dynamos. Sources of alternating voltage such as alternators and electronic circuits. Resistance and Ohm's Law. Power measurement and calculation for simple DC circuits. Electronics as control of electrons and other charged particles. Electromagnetic waves in space. Frequency of waves. Waveforms as shapes of voltage plotted against time. The sinewave. Pulses and effects of circuits that change pulse shapes. Differentiation ...
